However, as the use time increases, impurities in the water will clog the filter element, affecting the filtration speed and filtration effect. Taking the common PP filter element as an example, it needs to be replaced every 3 months, and the filter element needs to be replaced frequently. Utility Model Content

[0004] The purpose of the utility model is to provide a water filtering and purifying device to solve the existing problems raised in the above background technology.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a water filtering and purifying device, comprising a filter 1, a water inlet 2 is fixedly installed at one end of the filter 1, a mounting port 3 is fixedly installed at the other end of the filter 1, a threaded groove is opened on the inner wall of the mounting port 3, a collecting cup 4 is threadedly installed on the inner thread of the mounting port 3, a filter element 5 is arranged in the filter 1, a transmission rod 402 is rotatably installed in the collecting cup 4, an auger 403 is fixedly installed on the transmission rod 402, and the auger 403 fits the inner wall of the filter element 5.

[0021] In the present embodiment, clean water is transported to the interior of the filter 1 through the water inlet 2. At this time, the clean water will penetrate from the center of the filter element 5 to the outside, thereby filtering impurities inside or on the inner wall. The auger 403 fits the inner wall of the filter element 5, and the rotating transmission rod 402 can drive the auger 403 to rotate. The rotation of the auger 403 can scrape off the impurities accumulated on the inner wall of the auger 403 and transport them to the collection cup 4 for storage. This can extend the service life of the filter element 5 as much as possible and avoid the accumulation of a large amount of impurities on the inner wall of the filter element 5 that affect the filtration speed. At the same time, a power device is used to regularly drive the auger 403 to rotate, thereby achieving the problem of regular and automatic cleaning of impurities on the inner wall of the filter element 5 without the need for manual flushing.

[0022] In order to facilitate the removal of the collection cup 4, the device is implemented by the following technical solution: a water outlet 101 is fixedly installed on the filter 1, the water inlet 2 and the water outlet 101 are both connected to the inside of the filter 1, and a valve 201 is fixedly installed on the water inlet 2.

[0023] The water inlet 2 is connected to the water inlet pipe, and the water outlet 101 is connected to the drain pipe. The valve 201 can block the water inlet 2 to close the water inlet. There is no need to block the water supply by closing the main valve, which makes it easy to disassemble the collection cup 4 to dump the impurities inside.

[0024] Among them, in order to prevent the filter element 5 from deforming, the present device adopts the following technical solution: a motor 401 is fixedly installed under the collection cup 4, the output end of the motor 401 is fixedly connected to the transmission rod 402, a through hole 501 is opened in the filter element 5, an inner support frame 502 is fixedly installed in the through hole 501, and rubber sealing rings 503 are fixedly installed at both ends of the inner support frame 502.

[0025] By starting the motor 401, the transmission rod 402 can be driven to rotate, thereby driving the auger 403 to scrape off the impurities on the inner wall of the filter element 5. The inner support frame 502 is inside the filter element 5, mainly providing support for the filter element 5. First, it is prevented that the collection cup 4 is screwed in too much and squeezes the filter element 5 to deform. Secondly, after long-term use, the filter element 5, since the middle part of the filter 1 is hollow, the filter element 5 provides support, which can prevent the filter element 5 from being deformed internally due to long-term impact of water flow, resulting in the auger 403 being unable to fit the inner wall of the filter element 5. The rubber sealing ring 503 can contact the end of the collection cup 4 and the inner wall of the filter 1 respectively to seal the gap between the filter element 5 and the filter element 5 to prevent clean water from seeping out of the gap. The collection cup 4 is transparent as a whole, which is convenient for observing the internal impurity storage situation.

[0026] The working principle and use process of the utility model are as follows: when using, the device needs to be installed in a suitable position, the water inlet 2 is connected to the water inlet pipe, and the water outlet 101 is connected to the drain pipe. After the clean water enters the filter 1 from the water inlet 2, it is discharged into the water outlet 101 through the filter element 5. The impurities in the clean water will be retained on the inner wall or inside of the filter element 5. The motor 401 is started to drive the auger 403 to rotate. The rotation of the auger 403 can scrape off the impurities accumulated on the inner wall of the filter element 5 and transport them to the collection cup 4 for storage. After a certain period of time, the rotary valve 201 is turned to close the water inlet, and the collection cup 4 can be rotated to unscrew it and release the restriction on the filter element 5. At this time, you can choose to replace the filter element 5 or simply dump the impurities inside the collection cup 4 according to the usage of the filter element 5.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
